Screw Conveyor

Clean, Efficient & Continuous Bulk Material Handling

Highlights

Dust-free fully enclosed design
Flexible layout accommodates lengths up to 20 meters
Multi-process capability combines conveying, mixing, and cooling

Performance Features

Downtime Reduction and Quiet Operation

Enjoy smooth, uninterrupted material flow with elevated power transmission and whisper-quiet motor performance, keeping your facility compliant, efficient, and running continuously under heavy industrial loads.

Zero Clogging for Difficult and Sticky Materials

Choose shaftless configurations to eliminate material wrapping and severe clogging caused by wet sludge, biomass, or fiber-rich waste, drastically reducing manual intervention and maintenance labor costs.

Superior Corrosion Resistance and Sanitary Operation

Premium powder coating or stainless steel finishes safeguard your investment against aggressive corrosive agents, ensuring easy washdowns and extended equipment service life in grain and food applications.

Tailored Layouts and Multi-Process Consolidation

Optimize plant footprint by customizing pitch, diameter, and length every 0.5 meters, allowing you to combine material transport, mixing, and cooling inside a single compact machine.

FAQ

How do I select between a shafted and a shaftless screw conveyor?

The key lies in material characteristics. Shaftless conveyors eliminate the central shaft to prevent material winding, making them ideal for sticky or entangling materials such as municipal sludge, kitchen waste, and biomass straw. Shafted conveyors feature a classic design best suited for free-flowing, non-sticky dry powders and granular materials like cement and grain.

What is the maximum allowable particle size for conveying?

As a general rule, the screw diameter should be at least 10 times the maximum dimension of the largest material particle. If large particles account for only a small percentage of the total volume, requirements can be adjusted based on specific field conditions.

What incline angles and conveying distances are supported?

Standard conveyors accommodate horizontal routing or inclined conveying at angles under 20°. Vertical conveying configurations can also be customized with distinct engineering calculations. Single-unit lengths range from 3 to 20 meters in 0.5-meter increments, tailored to site requirements.

Can the system handle process functions beyond simple transport?

Absolutely. While transporting bulk material inside the fully enclosed casing, GSS screw conveyors can simultaneously perform mixing, stirring, or cooling operations, streamlining your processing line and reducing equipment investment.
